LOOK FOR THE MANUFACTURE OF TERRY FABRICS Filed Jan. :50. 1929 Patented Sept. 23, 1939 were RUDOLF Hit-DINA, OF CERVENY KOSTELEC, CZECHOSLOVAKIA Loom non. THE MANUFACTURE OF TERRY nannies Application filed January 30, 1929', Serial No. 336,202, and in Czechoslovakia-March 5, 1928-.

This invention relates to looms for the manufacture of terry fabrics and has for its object to provide certain improvements in looms of this type. As hitherto constructed the beat-up rods for these looms were either ordinary or multipart the latter being very. V

massive, as during adjustment in order to effect a complete or incompletebeat-up for the purpose of forming the terry they were l0 subjected to great stress. In the case of ordinary beat-up rods special devices for the formation of the terry were necessarily provided. known in which the effective length ofthe rod can'be varied by means of a lever or like mechanism, the beat-up rod journal of the moved portion being arranged to be moved in a. slot provided in the rod from one extreme position to the other. Moreover looms are also known for terry weaving in which the reed or reeds for forming the terry are moved through a certain distance by means of a suitable mechanism, which distance corresponc s to the length of the loops of the terry fabric to be produced.

constructions and devices'have the disadvantage that either they cannot produce an exactand uniform terry or the arrangements foreifecting the terry are very complicated. v

T he present invention provides a beat up rod for looms of this type which avoids the disadvantages hitherto encountered and the feature of the invention consists in providing on'the beat-up rod a latch which is adjustable in the direction of the rod journal, and which either falls into a second pivot on the rod journal or into an auxiliary pivot arranged on the carrier of the rod pivot.

In order that the invention shall be clearly understood it will now be described, by way of example, with reference to the accompanying drawings in which Figure 1 is a side view of the device with the latch member in the position in which it is in engagement withthe pivot of the rod at the time when an incomplete stroke of the batten is being effected.

Figure 2 illustrates the position of the rod at the time when the latch member is about to be raised from the plate or the like, so that, in

Beat-up rods for looms are also All the hitherto known.

order to effect a complete stroke it engages with the auxiliary pivot.

Figure 3 illustrates the position of the latch member after it has engaged with the auxiliary pivot for the complete stroke and member carrying the rod journal and the auxiliary pivot. j

Referring now in detail to the drawings, 1 is the oscillating lever, or support'upon which the batten is mounted. A hearing member 2 is secured to the lever, in the apertured members3, 4 of which the journal pivot 5 of the rod 6 is located. The rod. 6 is provided at its centralportion with a slot 7' and at the end directed towards the batten with a slot 8, in which a'pivot 5 is adaptedto move. At its other end the rod. is mounted in the usual manner on the driving crank. An axially adjustablebolt- 10 extends into the.

central slot and is secured in the adjusted position by means of a nut or the like. On the pivot 10 an oscillating latch member 11 is mounted, which has a recess 12 in its under edge and a reces 13 in its upper edge. A bracket 14 is mounted on the bearing 2 and secured by suitable neans and an auxiliary journallo is locatedin the arm a of the bearing member 2 and in the bracket '14. The latch member carries on its upper edge a' yoke 16 connected by means of a cord or strap 1'7 to the carding or acquard machine. To the under side of the latch 11 one end of a spring 18 is secured, the other end of which isconnected to the oscillating lever 1. The device operates as follows When an incomplete stroke is to be effected for the corresponding operation of the terry device, then the recess 12 of the latch will fall so as to be engaged by the pivot 5. The effective length of the rod 6 is thereby shortened as the pivot 5 is located adjacent to the inner end 'of the slot 8. hen a complete stroke is to be effected, the carding or jacquard machine, at the time when the crank and rod are in the position in which they are shown in Figure 2, raises the latch member 11 which oscillates in the direction of the arrow until the auxiliary pivot 15 engages in the recess 13. During further rotation of Figure ris a plan view ofthe supporting length of terry.

the crank 9, the pivot 5 will, by reason of the difference in the lengths of the radiiof the pivots 5 and 15 advance through the distance o. The length 11 almost corresponds to the distance between the centre lines of the recesses 12 and 13. Now a complete stroke is accomplished. hen the jacquard machine now lowers the latch lland vwhen the crank and rod are in the positionin which they are shown in Figure 2, the spring facilitates this return movement, as it always tends to maintain the latchmemberrin its lowest position.-

It will be evident that, in accordance with the construction of the jacquard plate, terry weaving can be carried out over a desired number of movements. The latch member ll may moreover be replaced by a latch member of different length or the pivots 5, 15 may beprovided at different distances from one another, in order to provide for a different These and other constructional alterations may be made; without departing from-the fundamental principle of the invention.

Having now particularly described and ascertained the nature ofmy said invention and in what manner the same is to be declare that what I claim is:

' 1'. In a loomfor the manufacture of terry fabrics means for varying the effective length of the beat-up rod during the operation of the loom. said means including a pivoted latch having recesses therein, a sliding rod pivot on the batten adapted to cooperate with one of said recesses and an auxiliary pivot for cooperating with another recess in said latch.

2. A device as claimed in claim 1 in which the-beat-up rod is provided with a central sfit'within which the latch pivot is adjusta e.

In witness whereof I have hereunto set my hand.
